CHIMES is a double blind, placebo controlled, randomized, multicenter study to test the hypothesis that NeuroAid is superior to placebo in reducing neurological deficit and improving functional outcome in patients with cerebral infarction of an intermediate range of severity.
The investigator(neurologist) has published a study in International Congress Series, in the 15th International Conference of Biomagnetism Vancouver Proceedings 2006,and Science Direct website, of 15 patients with brain ischemia and dilated ventricles who improve when treated with transcranial monitoring or low ultrasound wave intensity (milliwatts) and with rapid magnetic stimulation which is also a diagnostic tool routinely used by many neurophysiologists. Before, these patients will progress and may need a brain shunt called Ventriculo-peritoneal shunt. He and collaborators now would like to do a double study as this appears to be a cheap and effective alternative treatment and help patients to walk again.
Patients with stroke or transient ischemic attack (TIA) are at high risk of poor outcome, recurrence of cardiovascular events or vascular death.Until now, no reliable predictive biological marker could be identified in the acute phase of stroke.We hypothese that, in the acute phase of ischemic stroke or TIA, the increase of cardiac ( brain natriuretic peptide, BNP) or renal markers (albuminuria, cystatin C)might predict recurrence of cardiovascular events or vascular death. We want to assess which one of these markers has the best prognosis value , in a prospective study of 300 stroke patients followed during 3 years.
The purpose of this study is to determine the efficacy and safety of Betahistine Mesilate in the treatment of patients with vertigo caused by Cerebral Infarction in posterior circulation.
Hyperglycaemia is a frequent finding in acute ischemic stroke and associated with poor outcome. But the modalities of glucose lowering are still debated. This study will test the efficacy and safety of continuous intravenous insulin protocol versus usual subcutaneous insulin in acute ischemic stroke.
This study will recruit 316 ischemic stroke patients taking aspirin. They will be randomly assigned into cilostazol group or placebo group. Every patients will take 200mg of cilostazol a day or placebo for 1 month. The primary outcome variable of this study is rate of biochemical aspirin resistance on the Ultra Rapid Platelet Function Assay-ASA.
The main goal of the present study is to challenge the hypothesis that blood- brain barrier disruption following brain injury increases the risk for long-term disability, development of brain dysfunction, epileptic seizures and neuroanatomical alterations.
This study will determine the safety of 500mg of aspirin added to IV TPA at standard doses to prevent re-occlusion of cerebral vessels after successful reperfusion. In ischemic stroke brain arteries are occluded either by an embolus originating in the heart or large vessels leading to the brain or by a process of acute thrombosis of the cerebral arteries over a ruptured atherosclerotic plaque. Rupture of the plaque exposes thrombogenic elements within the plaque and leads to accumulation and activation of platelets and induction of the clotting cascade eventually leading to acute thrombosis and occlusion of the artery. TPA is currently approved by the Food and Drug Administration to treat heart and brain problems caused by blockage of arteries. It activates plasminogen and leads to disintegration of the thrombus/embolus. It is effective only if begun within 3 to 4.5 hours of onset of the stroke because of potential deleterious side effects including life threatening symptomatic intracranial hemorrhage (sICH) when the drug is administered outside of this time window. Reperfusion of the ischemic brain (i.e. timely opening of the occluded artery) with TPA is associated with improved outcome. However, in about 33% of patients that have successfully reperfused after TPA the artery re-occludes within the first few hours resulting in worsening neurological symptoms and worse functional outcome. This re-occlusion is speculated to result from re-thrombosis over an existing ruptured atherosclerotic plaque. This is explained by the relatively short half life of TPA leaving the exposed ruptured plaque intact which leads to re-activation of platelets and clotting factors and re-thrombosis. Thus, we hypothesize that the addition of an antiplatelet agent to TPA would result in lower rates of re-occlusion after AIS. The FDA approved TPA for patients with AIS but discouraged the concomitant use of anti-platelet or anti-thrombotic drugs for the first 24hours after administration of TPA because of concerns that such therapy may result in increased rates of intracerebral hemorrhage. Aspirin is a well known platelet anti-aggregant that works by inhibition of cycloxygenase 1 and reduction in thromboxane A levels. It has a rapid onset of action and additional potential beneficial anti-inflammatory effects in patients with AIS. The international stroke study showed that acute treatment of stroke patients with 500mg of aspirin is safe and feasible and results in better outcome. Furthermore, the drug was safe in these circumstances with an ICH rate of only . Therefore, the purpose of this clinical trial is to examine the safety and efficacy of the combination of aspirin with rt-TPA in patients with AIS.
The purpose of this study is to compare the safety and efficacy of treating individuals with acute ischemic stroke with normobaric oxygen therapy (NBO, given within 9 hours of symptom onset), to standard medical treatment.
